The 52-week range is explained in full in the entry 52-Week High and Low, which covers how the two figures are calculated, how traders use them and their limits. This page gives a short definition and explains why the two names exist.
The 52-week range is the band between the highest and the lowest price an asset has traded at over the previous 52 weeks, usually shown as two numbers ("12.40 – 31.75") or as the distance between them. Quote pages for shares and for coins on crypto price sites put it beside the current price, the market capitalization and the all-time high, so a reader can see at a glance whether the price sits near the top or the bottom of its recent history. A wide range relative to the price is a rough sign of high volatility.
"Range" describes the band as a whole, while "high" and "low" name its two ends, so the terms describe the same data and are covered together on one page. The figure applies equally to a stock and to a cryptocurrency such as Bitcoin; crypto sites calculate it on a rolling basis because those markets trade every day of the year.
